Description Pedro Sampaio 2019-04-02 19:19:06 UTC 
PDF creation script is vulnerable to Cross-Site Scripting (or "Code Injection") issues through which an attacker can inject arbitrary HTML code. For example during an invoice creation, an attacker can use its information written on the invoice to insert a malicious "link" tag pointing to a local phar archive and trigger a PHP Object Injection through the phar:// scheme once the web application reads that file.
